All answers are correct.

Explanation:

Genetic engineering is the procedure that includes the use of recombinant DNA technology to make changes in the genetic makeup of an organism, generally used in plants to increase the crop yielding and improving crops.

It includes various ways to includes modifying crops to reduced cost of production by large grains so icrease yield in limited cost. Improove the quality and nutrition value. Resistance to pests so their would less depend on fertilizer.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
